Fragments of hymns in honor of Attis have been preserved by Hippolytus
(_Philosoph._, V, 9. pp. 168 ff.) The so-called orphic hymns (Abel,
_Orphica_, 1883), which date back to a rather remote period, do not seem to
contain many Oriental elements (see Maas, _Orpheus_, 1893, pp. 173 ff.),
but this does not apply to the gnostic hymns of which we possess very
instructive fragments.--Cf. _Mon. myst. de Mithra_, I, p. 313, n. 1.

15. Regarding the imitations of the stage, see Adami, _De poetis scen.
Graecis hymnorum sacrorum imitatoribus_, 1901. Wuensch has shown the
liturgic character of a prayer to Asklepios, inserted by Herondas into his
mimiambi (_Archiv fuer Religionswiss._, VII, 1904, pp. 95 ff.) Dieterich
believes he has found an extensive extract from the Mithraic liturgy in a
magic papyrus of Paris (see _infra_, ch. VI, Bibliography). But all these
discoveries amount to very little if we think of the enormous number of
liturgic texts that have been lost, and even in the case of ancient Greece
we know little regarding this sacred literature. See Ausfeld, _De Graecorum
precationibus_, Leipsic, 1903; Ziegler, _De precationum apud Graecos formis
quaestiones selectae_, Breslau, 1905; H. Schmidt, _Veteres philosophi
quomodo iudicaverint de precibus_, Giessen, 1907.

16. For instance, the hymn "which the magi sung" about the steeds of the
supreme god; its contents are given by Dion Chrysostom, Oral., XXXVI, 39
(see _Mon. myst. Mithra_, I. p. 298; II, p. 60).

17. I have in mind the hymns of Cleanthes (Von Arnim, _Stoic. fragm._, I,
Nos. 527, 537), also Demetrius's act of renunciation in Seneca, _De
Provid._, V, 5, which bears a surprising resemblance to one of the most
famous Christian prayers, the _Suscipe_ of Saint Ignatius which concludes
the book of Spiritual Exercises (Delehaye, _Les legendes hagiographiques_,
1905, p. 170, n. 1).--In this connection we ought to mention the prayer
translated in the _Asclepius_, the Greek text {218} of which has recently
been found on a papyrus (Reitzenstein, _Archiv fuer Religionswiss._, VII,
1904, p. 395). On pagan prayers introduced into the Christian liturgy see
Reitzenstein and Wendland, _Nachrichten Ges. Wiss._, Goettingen, 1910, pp.
325 ff.

18. This point has been studied more in detail in our _Monuments relatifs
aux mysteres de Mithra_, from which we have taken parts of the following
observations (I, pp. 21 ff.).

19. Lucian's authorship of the treatise [Greek: Peri tes Sur
